Description
Technisches GebietTechnical area
Die Erfindung betrifft ein Verfahren zur Herstellung einer Dichtung, umfassend einen Dichtring und einen Gleitring, wobei der Gleitring auf der einer abzudichtenden Fläche zugewandten Seite des Dichtrings angeordnet ist und wobei der Dichtring und der Gleitring einstückig ausgebildet sind.The invention relates to a method for producing a seal, comprising a sealing ring and a sliding ring, wherein the sliding ring is arranged on the side of the sealing ring facing a surface to be sealed and wherein the sealing ring and the sliding ring are integrally formed.

Ein solches Verfahren ist aus der
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zu Grunde, ein Verfahren zur Herstellung einer Dichtung derart weiterzuentwickeln, dass dieses einfach und kostengünstig durchführbar ist.The invention is based on the object to further develop a method for producing a seal such that this is easy and inexpensive to carry out.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren gemäß Anspruch 1 gelöst.This object is achieved by a method according to claim 1.
Zur Lösung der Aufgabe ist ein Verfahren vorgesehen, das dadurch gekennzeichnet ist, dass in einem ersten Verfahrensschritt ein zylindrischer Rohrabschnitt aus dem polymeren Werkstoff des Gleitrings in die Werkzeugkavität eines Herstellungswerkzeugs eingelegt und in seiner Position gehalten wird, wobei der Rohrabschnitt die Werkzeugkavität in radialer Richtung in einen Gleitring-Hohlraum und in einen Dichtring-Hohlraum unterteilt, die einander in radialer Richtung benachbart zugeordnet sind, wobei der Rohrabschnitt eine axiale Breite aufweist, die im Wesentlichen der axialen Weite der Werkzeugkavität entspricht, dass in einem zweiten Verfahrensschritt elastomerer Werkstoff in den Dichtring-Hohlraum eingepresst wird, derart, dass der elastomere Werkstoff den Dichtring-Hohlraum vollständig ausfüllt und den Rohrabschnitt radial in den Gleitring-Hohlraum umformt, bis der Rohrabschnitt die den Gleitring-Hohlraum begrenzende Wandung anliegend berührt und dass die Dichtung anschließend in einem weiteren Verfahrensschritt aus dem Herstellungswerkzeug entformt wird. Dieses Verfahren ist einfach und kostengünstig durchführbar. Der Vorteil ist im Wesentlichen darin zu sehen, dass der elastomere Werkstoff, aus dem der Dichtring besteht, in den Dichtring-Hohlraum eingepresst wird und anschließend, wenn der Dichtring-Hohlraum vollständig ausgefüllt ist, den Rohrabschnitt selbsttätig radial in den Gleitring-Hohlraum umformt. Wenn der Rohrabschnitt die den Gleitring-Hohlraum begrenzende Wandung anliegend berührt, ist der Dichtring-Hohlraum und der Gleitring-Hohlraum jeweils weitgehend mit dem elastomeren Werkstoff des Dichtrings ausgefüllt, wobei sich der Gleitring und der Dichtring im Bereich ihrer Behrührungsflächen während des Herstellungsprozesses miteinander verbinden.To solve the problem, a method is provided which is characterized in that in a first process step, a cylindrical pipe section is inserted from the polymeric material of the sliding ring in the Werkzeugkavität a production tool and held in position, wherein the pipe section, the tool cavity in the radial direction in a sliding ring cavity and divided into a sealing ring cavity, which are associated adjacent to each other in the radial direction, wherein the pipe section has an axial width substantially corresponding to the axial width of the Werkzeugkavität that in a second process step elastomeric material in the sealing ring Cavity is pressed in, such that the elastomeric material completely fills the sealing ring cavity and radially deforms the pipe section into the sliding ring cavity until the pipe section contacts the wall bounding the sliding ring cavity and adjoins the seal d is removed from the production tool in a further process step. This method is simple and inexpensive to carry out. The advantage is essentially to be seen in the fact that the elastomeric material of which the sealing ring consists, is pressed into the sealing ring cavity and then, when the sealing ring cavity is completely filled, the pipe section automatically radially deforms into the sliding ring cavity. When the pipe section contacts the wall bounding the sliding ring cavity, the sealing ring cavity and the sliding ring cavity are each largely filled with the elastomeric material of the sealing ring, whereby the sliding ring and the sealing ring join together in the area of their contact surfaces during the manufacturing process.
Nach dem Entformen der Dichtung aus dem Herstellungswerkzeug liegt eine Dichtung vor, bei der der Dichtring und der folienartig ausgebildete Gleitring einstückig miteinander verbunden sind, wobei die Dichtung eine Elastizität aufweist, die ausreichend ist, die Dichtung auch in einteilige Einbauräume von Maschinenelementen zu montieren.After removal of the seal from the production tool is a seal in which the sealing ring and the film-like slide ring are integrally connected to each other, wherein the seal has an elasticity which is sufficient to mount the seal in one-piece housings of machine elements.
